As the summer brings with it warmer nights, one horrible side effect is that sleeping well can become harder and harder.
Getting comfortable before bed - especially as most homes in the UK don't have air conditioning - is a fine art. There are several things you can do to make it easier to drift off, from putting your socks in the fridge, to avoiding certain drinks before bed, but sleep experts have now recommended copying a popular trick that's common in other countries.
James Wilson, also known as The Sleep Geek, has revealed the hack he swears by to get a good night's sleep, reports The Mirror. He says the key to temperature regulation when the temperatures rise is to ensure you and your partner have separate duvets.
Speaking on behalf of Spin Genie, James explained: "If you have a partner, sleep with two duvets instead of one. Usually in Northern European countries, like Denmark or Norway, couples have two duvets, so each person has their own when sleeping.
"They think we in the UK are bonkers - why would you share a duvet? If you're a hot sleeper, laying next to someone, they're coming into your side of the bed, that makes you hot! Women in particular, because of the week before and during your period, your core temperature is a little bit too hot for sleep. So if you've got someone next to you, making you hotter, that's not good."
James continued: "Also, you might like a light duvet to sleep with, but your partner might still like a heavy duvet - one person in this relationship becomes the sleep dictator.
"That person says this is the duvet we're having and you can end up with 'duvet wars' where one person is saying, 'I've got the duvet, I'd like more of the duvet', or 'No, we’re having this [type of] duvet', you end up in this sort of battle. With separate duvets, they not only give a better temperature for sleep, but also stop you fighting over the duvet too. Win, win."
